I had an interesting, but inconvenient thing happen on a 650 mile ride. I hit a sharp bump, one of those that rattle your teeth, on the interstate going through a tunnel on I-77 and the bike backfired and died. I coasted to the shoulder, downshifted and popped the clutch and she fired back up. I noticed for the rest of the trip that when I would hit a bridge approach or bump in the road that was somewhat sharp the bike would cut out, so I began to watch the tachometer and sure enough it would drop a couple hundred rpm's instantly and quickly, it sort of bounced. Once it bounced from 3000 to 1000, but never died. I figured it might be a loose wire but could not find one out on the side of the Highway so I kept going. 30 minutes from home I hit another wonderful rough bridge approach and she died. I did everything I could to get her to start and she would backfire and make noise like I never heard before. It would start and run anywhere from a few feet to a 1/2 mile. I was about to give up when the crazy thing fired, backfired and then took me home as if nothing had happened. She is starting fine now, but not knowing makes me wary of going far from home.
My first thought as I said was loose wiring or other electrical, but after all was over I wondered if it might be that aggravating "Auto Fuel Valve" with which I have had previous issues. If anyone has any info. or suggestions I would appreciate them.

I had all most the same problem Sat. went out for lunch (Bob Evans) went out started my bike and It started running bad. I shut it off and restarted it again got back on highway headed for my Dads house. All the way tach shift indicator where going crazy and radio cutting in and out. Got to my Dads and let her cool off went back out and tried to start it but no go I pulled the side cover off and found the 30 amp fuse lose in the water proof fuse holder.I reseated it and checked screws retried starting all came back on and started ok ran fine for the rest of the day. Might want to also try and see with bike running wiggle the ignition wires at the bottom of your key switch and see if bike cuts out. Also check your kill switch as it too may be the problem. Good Luck Hal

I have checked with a couple of Mechanics who say when the Bank Angle Sensor goes it goes. Can anyone verify this in your experience? I have checked the fuses and am now checking for loose or frayed wiring coming from the pickup coils to the primary coils, etc. All suggestions are welcomed and appreciated.

Not true about when it goes it goes. You can bypass it to test. Also there should be an X engraved on the frame next to the sensor if it has been replaced by a dealer. If yours hasn't it is still under recall by Honda and any dealer will replace it.
Bypass it for testing. The connector is under the seat in the area directly below the passenger backrest. It's green. Trike conversions bypass that by jumpering the 2 outside wires to each other, on the end that comes from the front of the bike. (Don't remember the color but it is the outside wires)

i would be just riding along on the expressway and hit a bump and the engine would die. pull in the clutchturn the key off and back on then hit the start button and away i went. i rode all last summer like that but it was getting old and everyone was telling me to have the bank angle sensor replaced. i was at the dealer with a friend and asked the service rep to run my vin to see if the sensor had been replaced, he came back and said " no but its still under warrenty, are you leaving the bike today "? happy to report that i haven't had that problem since replacing the bank angle sensor

Hallelujah, I found the problem, it was a broken wire in the pulse generator harness. It was connected enough that it showed continuity, but when vibrated it would break contact. Took it for a test ride today over some bumpy road; not a miss. Thanks for the help, I am still going to have the bank angle sensor replaced by the dealer.
